Abstract
Selon la présente invention, la température d'un catalyseur (EHC) est estimée avec une haute précision. Ce dispositif de commande électronique commande un système de moteur comprenant : un moteur à combustion interne ; un moteur électrique apte à entraîner le moteur à combustion interne ; un catalyseur disposé dans un passage d'échappement du moteur à combustion interne, ayant une fonction de chauffage par excitation et de purification de gaz d'échappement ; et un capteur de température en aval disposé en aval du catalyseur. Le dispositif de commande électronique comprend : une partie de commande pour effectuer l'entraînement du moteur à combustion interne par le moteur électrique ; et une partie d'estimation pour effectuer un premier traitement d'estimation dans lequel la température d'un catalyseur est estimée sur la base d'informations détectées par le capteur de température en aval lors de la réalisation de l'entraînement du moteur à combustion interne.
